A li ati fil d November 24:, 1906. Serial No- 344,889

To all whom it may concern:

Be it known that we, HENRY N. BALCOM and GEORGE F. BALCOM, citizens ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented new and useful Improvements in Devices forAttaching Rubber Disks to Bottle-Stoppers, of which the following is aspecification.

This invention is a device for attaching rubber washers or disks tobottle stoppers.

The object of the invention is to provide an improved and simple meansfor doing this work. The implement is operated by foot power, to stretchthe washer or disk, to enlarge the hole therein so that the head of thestopper can be forced through the hole, the treadle being then releasedto allow the disk to contract around the neck of the stopper.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a front view of the implement. Fig. 2 is a side view. Fig. 3is a side view with the disk or washer stretched, and the head of thestopper being inserted therein.

Referring specifically to the drawings, 6 indicates a guide standardhaving a foot? bolted to a bench or table The standard has a verticalway or groove extending down the middle thereof, in which is slidable upand down a bar 8, connected by a strap 9 to a treadle 10. The bar isheld in the groove by cross plates 11 on the front, and it is normallyheld raised or at the upper end of the groove by means of a spring 12connected between a pin 13 on the back of the standard and a pin 14projecting rearwardly from the bar 8, through a slot in the standard.

At or just above the upper end of the groove in which the bar 8 slidesthe standard is provided with a forwardly projecting pin 15,substantially half round in shape, and the bar 8 carries a complementaryhalf round pin 16. When the bar is pulled up, the pins come together sothat the rubber disk may be easily slipped thereon, the pins extendingthrough the hole in the disk. Then by pulling the bar by means of thetreadle the rubber is stretched, elongating and enlarging the hole inthe disk so that the head of the stopper 19 may be slipped through thehole, and the disk may then be pulled off the pin by a smart forwardpull on the stopper, which disk then contracts into place in the grooveor neck at the head 01'' the stopper. When the treadle is released thespring lifts the slide bar and brings the pins together for a succeedingoperation.

We claim:

1. A device for attaching rubber washers to bottle stoppers comprising,in Combination, two members slidable with respect to each other, eachof'said members having a pin. which pins are movable with the members toand from each other, a spring connecting said members and acting tobring the pins together, and means to slide said members to separate thepins.

2. A device for attaching rubber washers to bottle stoppers having, incombination, a guide with a pin at one end thereof, and a slide in theguide having a pin at the corresponding end, said pins being in contactor separated according to the position of the slide, a spring connectedto the slide and acting to move the slide to bring the pins together,and means connected to the slide, to pull the pins apart.

3. In a device for attaching rubber washers to bottle stoppers. incombination. a standard having a groove therein and a pin at the end ofthe groove, and a bar slidable in the groove and having a pin at the endmovable to and from said pin, and arranged to stretch a Washer placed onthe pins. a spring connected to the bar and acting to lift the same tobring the pins together, and a treadle connected to the bar, to pull thesame down.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
